According to the Class 11 Physics Chapter 6 System of Particles and Rotational Motion, for a rigid body to be in complete equilibrium, two conditions should be met:

• Net external torque = 0 (rotational equilibrium)
• Net external force = 0 (translational equilibrium)

The condition for equilibrium in rotational motion ensures that the body is not rotating or accelerating linearly. It is important in engineering and static structures to maintain stability like buildings or bridges.

Yes, it is important to solve the Hydrocarbons ncert class 11 solved exercises for better understanding of topics. If the students faces any issue while solving the NCERT Class 11 Chemistry Hydrocarbons textbook exercises that means they must complete their conceptual knowledge.

The moment of inertia of a body about any axis to its moment of inertia about a parallel axis through the center of mass is the parallel axis theorem.
It states:
I = Ic + Mh2
Ic is the moment of inertia about the center
I is the moment of inertia of the body
h2 is the square of the distance between the two axes
M is the mass of the body

Mutually exclusive events are events that cannot occur at the same time. we commonally call these events disjoint events also. AS per the definition given in the class 11 math probability chapter;

Two events A and B are said to be mutually exclusive if: P (A? B)=0

For Example:
When rolling a single die:

Let event A = getting 2 on top

Let event B = getting 3 on top

Since the number on the top cannot be 2 and 3 at the same time, So A and B are mutually exclusive events.

Students can check the CBSE Class 11 Chemistry text book for NCERT solutions for class 11 hydrocarbons with diagrams. Students must practice the diagram solutions to master the questions.

Conditional probability is the probability of an event occurring given that another event has already occurred. 

It is denoted as:

$P (A|B) = \frac {P (A \cap B)} {P (B)} \quad \text { (provided } P (B) > 0\text {)}$

Where

P (A|B):  is the probability of event A occurring given that event B has occurred.

There are several other concepts which are really impoertant for acing the chapter, We recommend students to use our NCERT Solutions for Probability for the conceptual clarity and doubt solving.

Chapter 14 Probability carries a weightage of around 8 -10 marks in class 11 annual exam of mathematics, which itself is proof how important is this chapter. Students must cover all the basic to ensure maximum marks in the class 11 maths exams. Students can use our NCERT solutons for Probability provided by Shiksha to get step-by-step solutions of all the exercises.

Yes, Students can downoad the Probability solution PDF through the below given steps;

• Visit " NCERT Solutions for Class 11 Math Chapter 14 Probability
• Scroll and click on PDF section avalable on the page
• Click on the "Download Free PDF"
• PDF will appear on the screen, save it to desired location.

Students can check few of the important topics discussed in this chapter;

• Random Experiments , sample space, and the nature of random events.
• Definition and identification of events like simple, compound, sure, and impossible events.
• Types of Events: mutually exclusive events, exhaustive events, and complementary events.
• Algebra of Events: operations like union, intersection, and complement on events.

No, students must solve some extra NCERT Class 11 Chemistry Chapter 12 to understand what types of questions are prepared in the exam. Moroever, solving more questions will help to obtain a good marks.
